is sharp, and projects more than two lines beyond the incisors ; the eyes 

 are large and prominent ; the ears large and ovate ; the cheek-pouches, 

 when distended, reach to the ear ; the tail is scaly and hairy; the legs 

 and feet are stout. 



The fur consists of hairs either entirely black, or tipped with yellow- 

 ish or reddish brown ; the black hairs are the longest, and predominate 

 on the back and top of the head ; there is generally a blackish spot at the 

 roots of the whiskers, and a whitish one before the ear. The whiskers 

 are very long, some black, others white. The under parts, including the 

 legs, are pure white. 



This animal bears a considerable resemblance in form and colour to 

 Dr. Richardson's Mus. leucopus, which it rather exceeds in size ; but the 

 very evident cheek pouches distinguish it generically from Dr. Richard- 

 son's new species. 



This pretty little Hamster is very common in all the district, climbing 

 trees with facility, and making a nest of thistle-down in their hollows, 

 either towards the top or at the root ; it is quite a pattern of industry and 

 fore-thought, for, although it lays up a winter store of full half a peck 

 of corn or other seeds, it nevertheless runs about in search of food all 

 the winter, following the cattle track, and picking the undigested corn 

 out of their dung, regardless of deep snow or severe frost. It frequently 

 makes its nest in bams amongst the hay, where it also lays up its store. 



(46.) Meriones Labradorius (Richardson.) Jumping Mouse. 



The female makes a nest of grass ; my specimen had made her's under 

 the sod in a furrow, and had five young ones ; she measured 3| inches 

 from the nose to the insertion of the tail ; the tail itself 5 inches. 



(47.) Arctomys Empetra (Schreb.) Quebec Marmot. Ground 

 Hog of the settlers. 



This animal is solitary in its habits, and makes its burrow in dry sand- 

 banks. It is not uncommon. 



(57.) Sciurus Lysteri (Ray.) Chipmunk of the settlers. 



Very common. It is constantly seen running on the rail-fences, and 

 hiding among brush-wood, uttering a peculiar squeak when started ; 

 if hunted it runs up trees, but soon endeavours to descend, and by mak- 

 ing a great spring, tries to reach the ground and escape tc its burrow. 



(59.) Sciurus Hudsonius (Pennant.) The Chickaree Red Squirrel. 



It has no cheek-pouches, though placed by M, Cuvie: in the division
